Ireland sees lowest wholesale electricity prices since April, driven by strong renewable energy output

Electricity prices in Ireland continued to fall in June, with the average wholesale cost per megawatt hour dropping to €95.21—its lowest level since April 2024. This marks the fifth consecutive month of decline, according to a new industry report.

On days with high wind energy output, prices fell even further to €67.15 per megawatt hour, compared to €115.06 on days when fossil fuels supplied nearly all demand.

Wind farms provided 30% of Ireland’s electricity in June, while solar farms recorded their best month ever, boosting the overall share of renewable energy.

Electricity demand rose slightly compared to previous months, the report noted.

“Our members provided nearly a third of Ireland’s electricity during the first half of 2025,” said Noel Cunniffe, CEO of Wind Energy Ireland. “Last month was particularly strong for renewable generation.”

Cunniffe emphasized the economic and environmental benefits of renewables.

“Wind farms are Ireland’s leading source of clean electricity. They cut our reliance on imported fossil fuels and improve energy security,” he said. “Every turbine or solar panel pushing electricity into the grid helps lower prices.”

Since 2000, renewable energy is estimated to have saved Irish consumers nearly €1 billion in electricity costs. In 2024 alone, wind farms in counties like Kerry, Cork, and Mayo helped reduce Ireland’s gas spending by over €1.2 billion.
